CVE-2019-16746: Buffer Overflow
First published: Wed Sep 11 2019(Updated: )
Linux Kernel is vulnerable to a buffer overflow, caused by improper bounds checking by missing check of the length of variable elements in a beacon head by the net/wireless/nl80211.c. By persuading a victim to open a specially-crafted file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the system to crash.
